WATERPROOF-CLOSURE FASTENER Application filed. October 19, 1928. Serial No. 313,421.

This invention relates to devices for hermetically sealing bags of a flexible type, as rubber, for use by bathers.

Such bags or receptacles are of common use in carrying valuables, matches, smoking utensils and the like, by persons entering water for bathing and swimming, and it is obviously necessary that a water-tight closure be provided. 7

It is therefore an object of the present invention to produce such closure and to associate with it easily releasable means for maintaining it in operative position when the bag is closed. A further feature is in the provision of a closure retaining means adapted to re-enforce and strengthen the bag structure, rather than weaken it, and which does not detract from the appearance of the bag.

These objects are attained by the novel construction and combination of parts hereinafter described and shown in the annexed drawing, forming part hereof, and in which Fig. 1, is a partial side elevational view of a conventional type of bathers bag showing the improvement as applied, and the bag in an extended position, as ready to permit access to its interior.

Fig. 2, is an end view of the same.

Fig. 3, is a view similar to 1, but showing the neck of the bag as tightly rolled and the device for preventing immature unrolling and thus permittin leakage to occur.

Fig. 4, is an end view thereof.

The body 10 of the bag is preferably of the type using two similar sheets of rubber, soft leather or textile fabric rendered waterproof and cemented along their margins as indicated by the lines 1111.

The upper or throat portion 12 is provided with raised beads 13 on both of its extreme upper edges, and the main side portions 14 of the bag are extended as indicated. the side portions being supplied with narrow elongated slots 15 for convenience in attaching a support, such for instance as a waist belt.

The ordinary form of closure for such c evices consists of a tube 16, having a longitudinal slot 17 of such width as to closely lit over the upper edges of the throat, below and adjacent the bea s 13, acting as a clamp to retain the sides in close relation.

At the ends of the tube, which is equal in length to that of the throat, are formed forwardly extending, offset flanges 18 blending into further forward extensions 19, reaching upward, opposite the slot 17, considerably above the surface of the tube, these extensions constituting in efiect a pair of prongs adapted to be passed through the upper marginal portions of the bag side 14, after tightly rolling the neck upon the tube, as best seen in Figs. 3 and 4:.

It has been found that repeatedly passing '65 these prongs through the material Wears the slot and tears the bag sides due to their being thus weakened.

In the present case there is provided a pair of metallic clips 20 each having prongs 21 7 passed through the bag material at the sides and upset thereover to become firmly clinched.

The front or face portion of the clips is raised to present loops 22 below which the prongs 19 are inserted, after the neck has been coiled upon the tube, and it will be apparent that no wear can occur, while on the contrary, the clips furnish a decided reenforcement to the ba From the foregoing it will be seen that a simple device for this purpose has been disclosed in the preferred form of its embodiment, but it is not desired to restrict the details to the exact construction shown, it being obvious that changes, not involving the exercise of invention, may be made without conflicting with the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with a bag having flexible walls, an extending neck and sides, and a split tube in which the neck is engaged and on which it may be rolled, of looped clips fixed on the bag sides, and means at the ends of said tube to engage said clips.

2. The combination with an impervious bag and a tube roller at its mouth, of off:

set, upwardly projecting prongs 011 the ends of said tube, sheet metal l'eenforcing clips assed through and upset on the sides of the ag and loops raised from said clips to en- 5 ga e said prongs.

igned at New York, in the county and State of New York, this 15th day of October, 1928.
